Rainwater harvesting techniques

Rainwater harvesting is need of the day. We all are aware about water scarcity around the world including India. So, every raindrop matters a lot. Rainwater harvesting is an ultimate source here which helps in collecting rainwater and works against water crisis.

Rainwater harvesting:-

Collecting rainwater and storing it for later use is known as  rainwater harvesting. The water from rain is collected at various places such as on top of the roofs or on containers. A particular system which is established for harvesting rainwater is called rainwater harvesting system.

The basic idea behind rainwater harvesting is not to let the rainwater go waste.

A lot of effort goes to bring the rainwater back from the rivers and lakes where the rainwater gets stored, so the perfect solution is to harvest the rainwater. We should accept these techniques in our home so not a single drop of rainwater goes waste because every single drop of water matters, it will be possible only when we all will become punctual and implement the water harvesting system  at our home. We all have to take one step forward towards water harvesting.

Techniques of rainwater harvesting

Water harvesting can be done by various techniques, some of these major methods which are commonly used by people in their home are described below:-

1- Roof top harvesting-  This is the most popular technique among all the rainwater harvesting techniques which are used by people at home to collect the rainwater. Rainwater is collected at the roof  top of the houses which is then sent to the storage tank via slope pipes. The pipes run down the slope from roof into an underground tank. At the mouth of the tank a sieve is attached which filters the dust particles before the water gets into the tank, this is to ensure that the dust particles do not go inside the tank along with water. This technique is most efficient and popular in collecting pure rainwater at home.

2- Collecting rainwater in landscape holding area-  In this rainwater harvesting technique The soil dugged out from an area to be used for plants. This dugged out soil is used to make the banks or imbankment for a particular space to hold the water for plants. When the rainwater comes plants use the rainwater immediately before the water gets absorbed. It is also a very good technique which a suitable for plants growth. The main advanage of this technique is that it is not very expensive and do not requires much investment.

3-  Storing water in barrels or Containers -  In this technique the rainwater is collected and stored in various containers , which is later can be used for watering plants, lawns, washing vehicles and even for flushing toilets, although the water stored through this technique cannot be used for drinking but still it is a good technique because it prevents the wastage of water and each and every single drop of water is important. So all of us should store rainwater and this water can be used for any of the above purpose.

Therefore, it is important to store the rainwater from now onwards by using rainwater harvesting techniques, because if water is there then only we can live a life. Water crisis is increasing day by day before the water scarcity  reach the peak we should avoid the wastage of water and accepts the rainwater harvesting system. We must use water on sustainable basis so that our upcoming generation do not face water scarcity otherwise it will create problem for the coming generation.
